Appendix Cancer cases are rare.
It is estimated that approximately one thousand cases are diagnosed in the U.S. annually.
Symptoms* are often initially overlooked until they become problematic.
Appendix cancer, or appendiceal cancer, occurs when cells grow abnormally. The cells multiply out of control and develop a growth of tissue, described as a tumor. Tumor can be either non cancerous, or benign, or cancerous, or malignant. Appendiceal malignancies may be minimally invasive or aggressive. Malignant tumors may spread to other parts of the body.
Appendix Cancer tumors are generally divided into two groups: carcinoid and non carcinoid. These carcinoid tumors occur most often at, or near, the tip of the appendix.
Symptoms of appendix carcinoid tumors may include acute appendicitis when the patient is in his/her forties. Approximately half to two thirds of all appendix cancer tumors are carcinoid tumors. Carcinoid tumors originate in the hormone-producing cells that are usually present in small quantities in nearly every organ in the body.
Gastrointestinal carcinoid tumors form in cells that produce hormones along the lining of the gastrointestinal tract. These tumors usually appear in the small intestine, rectum and/or appendix. Gastrointestinal carcinoid tumors generally are considered to grow slowly, especially as when compared to other cancer tumors.
Non carcinoid appendix tumors originate in the epithelial cells lining the appendix. These cells may create mucinous producing tumors. This gelatinous mucin production may put patients at risk for the eventual spread of tumor cells and the accompanying mucin, throughout the peritoneal cavity. Over time, this mucin, and the cancer cells can eventually cause bowel obstruction, if left untreated.
Adenocarcinoid tumors of the appendix, also known as goblet cell carcinomas******, are similar to both carcinoid and adenocarcinoma tumors.
Approximately 20% of appendix cancer cases are categorized as Mucinous Cystadenocarcinoma. This type of tumor produces mucin that eventually fills the abdominal cavity causing distension, bloating, pain, shortness of breath and interference with digestive and bowel function.
A neoplasm is defined as abnormal tissue that grows by cellular proliferation more rapidly than normal cells, and continues to grow after the stimuli that initiated the new growth cease. Neoplasms show partial or complete lack of structural organization and functional coordination with the normal tissue, and generally form a distinct mass of tissue that may be either benign (benign tumor) or malignant (cancer).
Signet ring cell adenocarcinoma is a rare diagnosis and may be considered to be more aggressive and therefore more challenging to treat. Signet ring cell adenocarcinoma can develop in the appendix, colon or stomach.
Signet ring cell adenocarcinoma is considered to be the rarest and most aggressive of the appendiceal cancers and progresses more rapidly compared to other appendiceal cancers. Signet ring cell adenocarcinoma commonly presents with the same symptoms as all other appendiceal cancers, The treatment includes surgery and chemotherapy, including HIPEC and/or systemic chemo.
Acellular mucin within the abdominal cavity is described as Pseudomyxoma Peritonei.
Pseudomyxoma Peritonei is a mucin-producing tumor of the appendix. This is a condition in which cells have spread from the appendix and into the abdominal cavity. The Pseudomyxoma Peritonei mucin is very thick and viscous, often producing large tumors or clusters of tumors. These mucinous tumors enlarge causing bloating and abdominal distension. If left unchecked, mucinous tumors will eventually cause obstruction. The mucin must be surgically removed. If left untreated, tumor cells and mucin can increase with time, eventually resulting in bowel obstruction, when the areas of the abdominal cavity and pelvis normallyutilized for nutritional function and elimination, eventually become replaced by mucinous tumors.
The description of Peritoneal Carcinomatosis includes a variety of tumors that present with extensive metastasis throughout the peritoneal cavity. This description is used in conjunction with cancers and conditions of appendix, colon, gall bladder, ovaries, mesothelioma, pancreas, Pseudomyxoma Peritonei, rectal, sarcomas, small bowel, and stomach. When tumor develops from the peritoneum, it is referred to as Primary Peritoneal Surface Malignancy.
The prognosis** for Appendix cancer cases, when detected early, are often very good.
Treatment*** for appendix cancer include may include surgery with or without HIPEC or systemic chemotherapy

Appendix Cancer Symptoms*
What are the symptoms of appendiceal cancer?
How do I recognize Appendix Cancer symptoms?
Symptoms are often initially overlooked until they become problematic.
Symptoms may include pain in the lower right quadrant, bloating, abdominal distention, reflux, loss of appetite, digestive distress, appendicitis, appearance of a hernia, etc.
Symptoms of appendicitis may include inflammation, abdominal pain, swelling, vomiting, nausea, loss of appetite, constipation or diarrhea, and fever.
Due to an often common physical symptom of what is described as "expanding girth", male patients may intially be mis diagnosed with hernias while female patients may be misdiagnosed as having ovarian cancer.
The symptom or condition of ascites refers to the accumulation of fluid within the abdominal and/or peritoneal cavity. Ascites occur due a variety of benign and malignant conditions from inflammation to cancer.
Generally, the peritioneal cavity of a healthy adult includes approximately 100 ml. of pale colored, clear fluid. This fluid includes water, proteins, electrolytes and a variety of cell types. The cell types vary according to different pathological conditions. Lymphocytes in the fluid provide cellular, humoral, immunological defense mechanisms. The quantities and features of this fluid may change due to a variety of pathological conditions.
Diagnosis
How is Appendiceal Cancer diagnosed?
How does my doctor know I have Appendix Cancer?
If you, or a loved one, have been diagnosed with Appendix Cancer, ask your physician for a specific diagnosis of your particular condition. Obtain a copy of, and review your pathology* report.
Diagnosis may be suspected based on physical symptoms, CT scans, and tumor marker tests. However, the actual diagnosis is confirmed by pathologists after examination of actual tissue and/or mucin or fluid samples.
A "final diagnosis" paragraph will clearly define your specific diagnosis, which may possibly include Pseudomyxoma Peritonei, Mucinous Adenocarcinoma, Mucinous Cystadenoma, Disseminated Peritoneal Adenomucinosis or DPAM, Signet Ring Cell Carcinoma of the Appendix****, Peritoneal Carcinomatosis, or other diagnoses.
Refer to our diagnostics page and to our PMP Pals' Network Handbooks for additional detailed information describing laboratory and imaging testing.

Appendix Cancer Diagnosis
Prognosis and Long Term Survival**
What it the prognosis for Appendix Cancer patients?
What are the long term survival statistics for Appendix Cancer patients?
How long will my love one survive with the diagnosis of Appendix Cancer?
The prognosis for patients diagnosed with appendix carcinoid tumors***** is often good.
Appendix carcinoid tumors, located at the tip of the appendix, of less than two centimeters, generally have a low risk of spreading to the lymph nodes.
Many factors contribute the prognosis. These factors may include pathology, staging at the time of diagnosis, overall health of the patient at the time of the diagnosis, age at the time of diagnosis, access to specialized care, etc.

Appendectomy, combined with periodic monitoring by a surgical oncologist specialist, may be adequate treatment for these some cases. Appendectomy is the surgical removal of the appendix. A surgical oncologist is a surgeon who specializes in treating cancer.
Clinics and hospitals specializing in Appendix Cancer carcinoid treatment are listed on our Surgeons & Specialists link.
Treatment for appendix cancer*** include may include surgery with or without HIPEC or systemic chemotherapy.
Cytoreductive surgery (CRS) refers to the removal of tumor and mucin within the abdominal or peritoneal cavity. It is possible that some organs, or portions of organs, will also be removed.
Hyperthermic Intraperitoneal Chemotherapy (HIPEC) may be included at the conclusion of the cytoreductive surgery. HIPEC is administered with the infusion of heated chemotherapy during the last 90 minutes of the CRS procedure. Through HIPEC the surgeon(s) intend to destroy any residual tumor cells that may not have been surgically removed during CRS.
Your surgeon specialist (surgical oncologist) will explain and review all treatment options for Appendix Cancer with you. Your treatment plan will depend on your overall health, the size and location of the tumor, the type of tumor and whether the cancer has metastasized.

Surgical Treatment for Appendix Cancer
The purpose of debulking surgery for appendix cancer treatment is to remove as much tumor as possible. Debulking often includes the removal of the omentum and the right colon. Additionally, for women, debulking will likely include a hysterectomy, if this was not previously performed. Adhesions may more troublesome with any additional debulking surgeries.
Treatment utilizing cytoreductive surgery includes thorough removal or destruction of all visible tumors throughout the surfaces of the peritoneum or peritoneal cavity. Surgery may include the removal of segments of small and large bowel, gall bladder, liver, omentum, ovaries, pancreas, spleen, stomach and uterus. Although this procedure may initially sound drastic to the newly diagnosed patient, rarely is resection and/or removal of all of these organs is required. The degree, or extent of resection, depends on size and location of the tumors(s).
Each patient's case is unique and most patients live productive and healthy lives following surgery.
Cytoreductive surgery is a detailed, lengthy procedure often requiring ten or more hours.
Tumors are removed and destroyed using a variety of surgical techniques including argon beam coagulator, electro-evaporation, laser, and ultrasonic dissection.
Optimal results are achieved per the surgeon's ability to remove all visible tumor, with minimal, if any, deposits of residual disease. Less residual tumor may result in a better the opportunity for HIPEC to be effective.
Appendectomy refers to the surgical removal of the appendix. Appendectomies may be performed via laparscopy.
Hemicolectomy is a surgical procedure involving the removal of a portion of the colon next to the appendix. This procedure may also include the removal of nearby blood vessels and lymph nodes at the same time.
Peritonectomy refers to stripping the parietal peritoneum and resecting structures at the sites that contain adenomucinosis.
The peritoneum is the transparent serous membrane lining the cavity of the abdomen.
Ostomies: some patients require a temporary or permanent ostomy to assist them during recuperation.
The PMP Pals' Network provides many helpful resources, as well as Pal Mentors to assist you with your ostomy!

Systemic and HIPEC Chemotherapy Treatment for Appendix Cancer
Systemic chemotherapy targets cancer cells throughout the body and is delivered throughout the bloodstream.
Is systemic chemotherapy an appropriate treatment for you? Review our Diagnostics page for more information about KRAS mutation testing, etc.
HIPEC or Hyperthermic Intraperitoneal Chemotherapy, for treatment, may be administered if complete tumor debulking is accomplished through cytoreductive surgery. HIPEC includes the infusion of the abdominal cavity with a specific chemotherapy, heated to approximately 40 degrees Celsius for a period of approximately 90 minutes. The purpose of HIPEC is to attempt to kill any appendix cancer carcinoid tumor cells which were not removed during the actual surgery process.
Hyperthermia refers to the high temperature administration of chemotherapy agents.
he heating of chemotherapy increases the penetration of into tissues and may be used to damage and destroy cancer cells.
